Flash in UEFI only NOT in windows environment.

@MeatWar, thank you! I really do appreciate the help.

NVMe got in there quickly and with no issues. "PCI-e – M.2" adapter and everything working good, bootable, OS loading.
Intel ME didn't want to get updated at all. Don't know why. Tried DOS\UEFI, AFUDE238, MSI Forum Flashing Tool, M-Flash and even FWUpdLcl.exe from Intel ME System Tools v8 r3, but only direct flash via FPT resulted in successful ME version update (the only thing that currently it does not pass the tests of "MEManuf.exe" from ME System Tools set). But to hell with it :)
